Product Summary
The Allen-Bradley 1762-IQ32T expands any MicroLogix 1100, 1200, or 1500 system with thirty-two 24VDC discrete input channels. Four isolated groups of eight channels each enable flexible wiring. This module supports both sink and source configurations.
Why the 1762-IQ32T Fits Your Procurement Needs
Procurement managers must match module capacity to field device count. The 1762-IQ32T provides 32 inputs in one compact DIN-rail package. Each group contains eight channels with independent isolation. This design reduces the total number of modules required.
You gain a nominal voltage of 24VDC with a wide operating range of 10 to 30VDC. The module accepts both sinking and sourcing field devices without extra adapters. This flexibility simplifies inventory management and reduces wiring errors.
The module draws only 170mA from the 5V backplane and zero from 24V. Low power consumption means you can add more I/O without overloading the power supply. The 1762-IQ32T dissipates 5.4 to 6.8W of heat.
Expert Technical Evaluation: Signal Integrity and Isolation
Engineers rely on precise input detection for machine safety. The 1762-IQ32T delivers an 8ms On-transition signal delay. This consistent timing supports reliable high-speed monitoring of limit switches and sensors.
Isolation between input groups and backplane exceeds 1200V AC for two seconds. Reinforced insulation at 75VDC working voltage meets IEC Class 2 standards. Such isolation prevents ground loops and protects the controller from surges.
The module uses bit positions 0–15 of words 0 and 1 for all 32 inputs. This memory mapping simplifies programming in RSLogix 500. Each channel requires a minimum On-state voltage of 10VDC and a minimum On-state current of 1.6mA.
How to Choose the Right Configuration
Application engineers must verify controller compatibility first. The 1762-IQ32T works with MicroLogix 1100, 1200, and 1500 controllers. It connects via the 1762 bus interface and receives 10, 24, or 30VDC power.
Mount the module on a standard DIN rail using the provided locking tab. The finger-safe cover protects wiring terminals during operation. A single status LED indicates power presence and helps identify faults quickly.
For high-vibration environments, use the 1762-IQ32T in non-hazardous, dry, and clean areas. Avoid crossing circuits over Voltage Category II standards. Always remove power before installation or removal.
